低或中等强度的可见光长时间照射能损伤视网膜。这是一个复杂的病理生理过程。有关光损伤的阈值,影响因素和作用机理正在研究中,同时也不断提出了各种防护措施。本文就此作一介绍。一、光损伤的影响因素近二十年对视网膜光损伤的研究发现,损伤的发生、发展、程度和恢复等过程受到诸多因素的影响,主要来自照射光源及条件和受照对象两个方面。 Low or moderate intensity of visible light for a long time can damage the retina. This is a complex pathophysiological process. The threshold of light damage, the influencing factors and the mechanism of action are under study, and various protective measures are constantly put forward. This article makes an introduction. First, the impact of light damage Nearly two decades of studies on retinal light damage found that the occurrence of damage, development, extent and recovery and other processes are subject to many factors, mainly from the light source and conditions and subject two aspects.
